This is a difficult question to answer since we spray apply different types of foams that have various costs associated with them. Commercial builds, new homes, old homes, basements, crawl spaces etc all have variables that need to be accounted for.

The best thing for you to do is call in and we can see what your individual needs are and price the project accordingly. No one can throw square foot numbers out accurately.

 

Spray Jones Inc. has many new home builders that are well versed in our services and if you are building with them they can forward your plans to us for pricing.

If you are building the home yourself or with a builder we have not yet worked with we will need a full set of plans to look at. We then meet with you and discuss your needs and plans for development and from there compile a price.

 

No.

But that being said nearly any building product can do damage to other components if installed improperly. Walltite spray foam has been extensively tested by Underwriters Laboratory of Canada (ULC) to confirm the affects on non-metalic covered cables. When installed to the ULC standard tested no harm will be done with CSA certified wiring and electrical components.

 

Medium density and low density foams will stick to nearly any clean dry surface. Ice, grease, dust and wet surfaces will not allow adhesion and some very smooth plastics can pose a difficulty but they can be overcome with a primer.

Adhesion pull tests on done on the first and second passes of foam (for medium density) at varios random intervals to ensure a consistent installation.

 

No.

Spray foams of any kind need to be covered with a 15 minute thermal barrier. In most cases this is drywall. So at some point you will need to plan on covering the foam to be in compliance with the fire codes.

In agricultrial buildings the issue becomes insurance. Although not being forced by a fire code to cover the foam, many underwriters will not insure buildings leaving SPF exposed.

 

No.

There are some companies that have tried to claim success with this but it is our experience that foam needs to be installed into open wall cavties. For good reasons:

The CCMC certified foams on the market today like Walltite are spray formulations and not pour. They rise and set in seconds not minutes. Also when filling an enclosed wall the foam will take the path of least resistance and this can mean bowing the walls out instead of rising up. Also many older homes that this process seems appealing to have fire blocking at intervals and thefore making it difficult to precisely install the needed insulation.

 

First thing to know is that there are two types of foams being installed into homes in Canada.

First is medium density foam like Walltite. This product uses inert gases other than air to insulate with. The gas is trapped in the cell and held there for a lifetime. This being said the foam is always rated in aged terms known as "Long Term Thermal Resistant Values" or LTTR for short.

Walltite has the following LTTR ratings for thicknesses:

1" = R6.3

2" = R13.1

3" = R20.4

4" = R29.2

Low density foams are water blown and use steam to make the cells rise and traps carbon dioxide in the cells. These foams do not have LTTR ratings and the range from R 3.1 - 3.8 per inch.

 

Polyurethane foam was first invented in the 1940s during WWII by the Bayer Corp. to strengthen aircraft wings. From there building began to have foam sprayed into them as early as 1969.

In Canada the National Building Code of Canada first recognized sprayed polyurethane foam as an insulation material in 1985. Each successive code update has had more reference to foam plastics in it 1990, 1995, 2005 NBC respectively.

Polyurethane foam has been in consumer products for decades. Seat cushions, doors, mattresses, fridges, coolers etc. It is all around you and most people take it for granted.

 

Yes spray foam will burn. However it will not support a flame. This means that the foam has not fuel value in a fire. It needs something else burning in order for it to be consumed. When burned in the lab foams self extinguish. Once the flame is removed the fire goes out.

In Canada foam plastics need to pass the Can/ULC S102 corner wall test. This is a pass or fail test measuring flame spread index and smoke development. One cannot have a CCMC certified foam without passing this test.

 

All smoke is toxic. In Canada there is no test devised to test building materials or consumer products for smoke toxicity. The smoke from red oak flooring will kill you as will the smoke from one light switch cover plate.

 

That depends on the type of foam being used, low density foams need to be thicker while medium density will be thinner. It also depends on the area that it is being sprayed to and the end result.

Spray Jones Inc. staff will always discuss your needs with you and write a proper specification based on budget, building codes and end results desired.

 

If the foam is not properly installed anything is possible over time. Also if the there is a contaminate on the wood foam's adhesion can be compromised over time.

However, when properly installed and on a clean and dry substarte there is no reason for the foam to pull away. The movement of building materials that are structurally sound cannot exceed the elongation and tensile strength of the foam. BASF backs this up with a warranty for Walltite.

Remember foam is used as an integral part of structural panels like garage doors and has been extensively used in ready to move homes (RTM). These homes see the most severe flexing of the walls and ceilings with foam installed in them. Sprayed polyurethane foam is after all urethane. Urethane is one of the best construction adhesives known.

 

No. Shingle life is dependant on many things; colour, direction of face and style of manufacture are the biggest. Remember that the attic with Walltite applied to the roof deck is not hot during the summer. It stays within 2-4 degrees of the thermostat setting. If the attic is cool that means that all is left to heat the shingle is the sunlight. This is the same direct sunlight that is present even with a vented assembly. For more info on this check out "the value of ventilation" in the facts and details section.

 

No, so long as the correct thickness is sprayed on the substrate. Some foams on the market are open celled and they require vapour barriers, as do medium density foams that do not have CCMC air barrier material certification. Nevertheless a complete air infiltration caulking package is 100% needed to ensure a seal where wood meets wood before the drywall is installed.

 

Yes, BASF offers for new homes or commercial buildings a standard 2 year warranty on the material and mandates us to follow up with one year on the installation.

 

As long as the foam is applied correctly and that it is CCMC certified foam in your home or building and installed by a qualified, licensed installer and company there is no reason it will ever have to be removed. When the issues with UFFI arose it only took the industry three years to discover the problem and then ban its use. Walltite has been around in formulation format since 1969 and sold under the name Walltite since 1995. The building code full recognizes it under the ULC S705.1 standard.

 

Small areas can be fixed up with commercially available can foam. Larger areas many require that of a do-it-yourself froth pack. This is a twin component system with short hose and plastic gun. Rigid board insulation can also be cut to fit the area and sealed into place.

 

There is no such thing. A jet airliner is as tight as it gets and it does not have moisture and humidity issues. The reason is the HVAC system has been properly loaded to account for this. Your home will need to be designed the same way. Most plumbing and heating companies have switched to computer aided software that loads the home and tells them what to install so issues don't arise.

 

Never mix qualifications with certification. Someone may tell you they are qualified due to years of experience but not have a CCMC certified foam. In turn they may have a CCMC certified foam but very little experience. Check references and reputations before making a choice; also experience cannot be bought. If someone cannot answer your questions or sounds green you best move on. It is buyer beware now with many people trying to cash in on spray foam's popularity.

 

Anywhere from 2 days to 3 weeks depending on the size. It also depends on how many units we send to a job site and the distance from the office. Average homes are under 6 days of spraying. After looking at your plans and discussing your needs Spray Jones will answer this question accurately for your home.
